Question

Assumindo que a frequencia da onda detectada no ligo tenha sido 250Hz, qual seria o omprimento de onda dessa onda gravitacional em Quilometros?

Answer 1

$\textrm{Sabemos que:}\\\\ \mathrm{f=250\ Hz=2,5.10^2\ Hz}\\ \mathrm{c=3.10^8\ m/s=3.10^5\ km/s} \\\\ \mathrm{c=\lambda.f}\ \to\ \mathrm{3.10^5=\lambda.2,5.10^2\ \to\ \lambda=\cfrac{30.10^4}{2,5.10^2}}\\ \mathrm{\lambda=12.10^2}\ \to\ \mathbf{\lambda=1200\ km}$
